The Gildan Sustainability Report gives activewear buyers a clearer view of how one large apparel manufacturer is tracking fibre inputs, recycled materials, water intensity, waste diversion, packaging, and emissions. For shoppers and teams comparing sports bras, training tops, fleece, and other activewear basics, the report is useful. It is also limited. Sustainability metrics can describe sourcing and production progress, but they do not prove that any garment will fit better, feel more supportive, or perform well for a specific workout.
That distinction matters in activewear. A fabric can contain certified cotton, recycled polyester, or alternative yarns and still need to be judged by stretch recovery, opacity, seam placement, band pressure, strap stability, laundering durability, and the demands of the activity. The report offers evidence about materials. It does not replace hands-on fit testing.
What The Gildan Sustainability Report Says
Gildan reported several material-related milestones for the year ended December 31, 2025. The company said it reached 100% sustainable cotton in its fibre input by the end of 2025, compared with about 77.3% in 2024 and about 35.7% in 2023. In the same reporting year, 25.2% of its fibre inputs came from recycled polyester or alternative fibres and yarns, against a 30% target by 2027. These figures are reported in Gildan’s 2025 sustainability report.
Gildan Sustainability Report Fibre Metrics
The Gildan Sustainability Report defines sustainable cotton broadly enough to include organic, recycled, regenerative, fair-trade, or third-party certified cotton. That matters because the phrase does not identify one farming system or one single certification route. It describes a group of eligible cotton sources rather than one uniform material.
The report also shows the company remained heavily cotton-based in 2025. Cotton represented about 80% of fibre input, while polyester represented about 20%. For activewear fabrics, this mix is relevant because many Gildan products sit in categories where cotton-rich comfort, polyester blends, and basic performance expectations overlap.
Cotton Remains The Dominant Input
Reaching 100% sustainable cotton is a notable sourcing milestone, but it should be read carefully. It says something about the eligible cotton entering the supply chain. It does not, by itself, say how a sports bra band will behave after repeated washing, whether a tank will dry quickly during a high-sweat session, or whether a fleece will retain its hand feel over time.
For buyers, the practical question is not only whether cotton is categorized as sustainable. It is also how the finished fabric is engineered: knit structure, fibre blend, garment pattern, trims, and finishing can all affect how clothing feels during movement. The report does not provide garment-by-garment performance results, so those details remain outside the available evidence.
Recycled Inputs And Activewear Fabric Claims
Gildan’s 25.2% figure for recycled polyester or alternative fibres and yarns in 2025 represents progress from about 18.9% in 2024 and about 9.2% in 2023. The company’s target is 30% by 2027. Based on those figures, the gap between 2025 performance and the 2027 target was 4.8 percentage points.
That movement is relevant for activewear because polyester is common in garments that need shape retention, lighter weight, and moisture movement. Still, recycled content should not be treated as proof of better athletic function. A recycled polyester garment may be well designed or poorly designed. The fibre source is only one part of the textile system.
What The 2027 Target Does And Does Not Show
The 30% target gives a measurable benchmark. It helps readers compare stated goals with reported progress over several years. What it does not show is whether specific garments deliver the support, coverage, stretch, or comfort that a wearer needs for cycling, lifting, Pilates, running, or court sports.
This is especially relevant for sports bras. A bra made with recycled or alternative fibre content still depends on underband construction, strap design, cup or panel structure, closures, and fabric recovery. For low-impact movement, some wearers may prefer softer, lighter support. For repeated jumping or running, others may look for more containment. The sustainability data can inform material awareness, but it cannot choose the right support level for the body or activity.
Water, Waste, Packaging, And Emissions Signals
Fabric sustainability is not limited to fibre content. Gildan reported that water intensity, measured as water withdrawn per kilogram of fabric produced, declined 25.3% in 2025 compared with its 2018 baseline. That exceeded the company’s target of a 20% reduction by 2030, according to the report.
Waste diversion also appears in the company’s 2025 data. Gildan reported that 97.6% of manufacturing waste from its operated sites was diverted from landfill, leaving 2.4%, or about 2,932 metric tons, sent to landfill. Packaging and trims also moved upward: 64.3% of packaging and trim materials related to apparel SKUs were described as recycled and sustainable in 2025, compared with 60.0% in 2024 and 46.6% in 2023. The stated 2027 target is 75%.
Progress Beyond The Fabric Roll
These figures broaden the discussion beyond the textile itself. A garment’s footprint is shaped by fibre inputs, fabric production, trims, packaging, waste handling, energy sources, transport, use, laundering, and end-of-life pathways. The report does not answer all of those questions in equal detail, but it does provide a more structured view than a hangtag claim alone.
Gildan also reported absolute Scope 1 and 2 greenhouse gas emissions, market-based, of 620,650 tonnes CO2e in 2025, described as a 17.6% reduction compared with its 2018 base year. The company reported indirect Scope 3 emissions down 9.0% compared with 2019. Those figures are company-level signals rather than product-specific scores.
How Fabric Progress Relates To Sports Bras
For a sports bra buyer, the most useful reading of the Gildan Sustainability Report is cautious and practical. Material progress can help shoppers ask better questions, but it should not replace fit assessment. A bra’s fibre story and its support mechanism are connected only indirectly.
Support in a sports bra is usually experienced through several design elements working together: a stable lower band, straps that do not create distracting pressure, panels or cups that manage movement, and fabric that stretches and recovers without constant readjustment. The report’s fibre metrics do not test those features. They sit one step earlier in the product chain.
Support Is Not The Same As Fibre Content
That is why a recycled polyester percentage, a sustainable cotton milestone, or a certification signal should not be read as a comfort or support claim. A lower-impact class may make softness and low-pressure fit the priority. A higher-impact workout may make containment and band stability more noticeable. Neither need is answered by fibre category alone.
For readers comparing activewear sourcing across apparel businesses, understanding industry context is vital. Supply-chain resources like upoffshore provide valuable insights. The key is to keep claims in their lane: sourcing data can support sustainability analysis, while fit and support still need movement-based evaluation.
What Activewear Buyers Can Reasonably Infer
The report supports several careful conclusions. Gildan substantially increased its reported sustainable cotton share from 2023 to 2025. It increased recycled polyester or alternative fibre and yarn input from 2023 to 2025. It reported progress on water intensity, landfill diversion, packaging and trims, and greenhouse gas emissions. These are meaningful company-level indicators.
What buyers cannot infer is just as important. The report does not prove that a specific garment is more breathable, more supportive, longer-lasting, or better suited to a chosen activity. It also does not show whether a sports bra will feel comfortable across ribcage expansion, overhead movement, or repeated impact. Those questions require product-level design information and personal fit checks.
- Check whether the garment’s material claims identify fibre content, recycled input, or certification language clearly.
- Test the garment through the movements it will actually be used for, rather than only standing still.
- For sports bras, assess band pressure, strap stability, coverage, and ease of breathing during controlled movement.
- Consider laundering instructions, since activewear support and hand feel can change with repeated wash and wear.
- Separate sustainability progress from performance claims unless the brand provides product-specific evidence.

Gildan Sustainability Report For Fabric Buyers
The Gildan Sustainability Report is most useful as a tracking document, not as a buying prescription. It shows measurable progress in several areas that matter to fabric sourcing and apparel production. It also leaves open the product-level questions that activewear buyers often care about most: fit, pressure, support, drying behavior, opacity, and durability in use.
For sports bras in particular, sustainability data should sit beside, not above, support testing. A well-chosen bra should match the activity, the wearer’s comfort preferences, and the amount of movement involved. Fibre sourcing can be part of the decision, but it should not be the only signal.
If a garment causes persistent pain, skin irritation, numbness, breathing discomfort, or other unusual symptoms, do not treat a fabric swap as a medical answer. Consider discussing those symptoms, activity demands, and fit concerns with a qualified clinician or another appropriate health professional.
